Applying this into omap-for-v4.5/dt.. But I'm getting concerned about this
"regulator-always-on" stuff and having multiple copies of the same thing.

I think we should have a common am33xx-tps65217.dtsi file that has the
regulators defined at one place and other then include it. And they are
controllable AFAIK..
